- <h2 id="data-structure">Data Structure</h2>
 
- <p>Bubble chart datasets need to contain a <code>data</code> array of points, each points represented by an object containing the following properties:</p>

-     <span class="hljs-comment">// X Value</span>

-     y: <Number>,
 
-     // Bubble radius in pixels (not scaled).
 
-     r: <Number>
 
- }
 
- </code></pre>
 
- <p><strong>Important:</strong> the radius property, <code>r</code> is <strong>not</strong> scaled by the chart, it is the raw radius in pixels of the bubble that is drawn on the canvas.</p>
